Interesting Insects

29th June 2025 - there have been a number of sightings recently of what has been described as a bright red 'butterfly', and which have been identified as Scarlet Tiger Moth. At rest, these moths have a dark-green sheen to the wings, with a number of white, yellow or orange spots. The hindwing is hidden while at rest, but is the bright red colour evident when the moth is disturbed or in flight. They fly both in daylight, particularly in late afternoon, and also at night in May and June.

A small Bush Cricket, only about 1cm long, was spotted by Polly M resting on a Day Lily flower.

And a group of rather strange-looking smooth grey 'caterpillars' were spotted by Roger D in his garden, these being Solomon Seal Sawfly larvae. Related to bees, ants and wasps (Hymenoptera), these Sawflies lay their eggs on Solomon Seal (Polygonatum) plants, and the emerging larvae can quickly defoliate them. The adult fly is around 1 cm long, and all black.

Protected Road Verge flora

27th June 2025 - David F reported that the Field Scabious and Greater Knapweed were both looking good at the moment, in what is otherwise a dry verge, with Ragwort also being quite prominent.

River Sampling, June results

26th June 2025 - the RiverCare team undertook their regular sampling of the river Granta wildlife, at the Abington Ford. The regular sampling gave only a low number of creatures, although not low enough to trigger a resampling event.

Flora on the Old Railway Cutting

20th June 2025 - a few less common plants showed themselves along the disused Old Railway Cutting recently.  A Pyramidal Orchid was found flowering along the top of the bank by the path - a species not seen along there in recent years. Also a Knapweed Broomrape, this plant being unusual in that it doesn't produce leaves or have chlorophyll, thus its pallid completion - instead it gets its energy by parasitising the roots of other specific plants, in this case knapweed. Finally, the large airy seed head of Goat's Beard, looking like a giant dandelion clock.
